Question

solve this linear equation x - 40% of x = 12​

Answer 1

Step-by-step explanation:

x - 40% of x = 12

x - 40÷100 × x = 12

x - 2/5x = 12

3/5x = 12

x = 12×5/3 = 20

Hope the answer will help you.

Answer 2

The answer is, x = 20

Given : The linear equation is, x - 40% of x = 12

To find : Solving the linear equation.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to solve the given linear equation)

Here, we will be solving the equation for variable x.

So,

x - 40% of x = 12

x - (x × 40%) = 12

x - [x × (40/100)] = 12

x - (2x/5) = 12

(5x-2x)/5 = 12

3x/5 = 12

3x = 12 × 5

3x = 60

x = 60/3

x = 20

(This will be considered as the final result.)

Hence, the answer is, x = 20
